Have been feeling good for about 6 weeks, things were pretty much back to normal. Then suddenly starting to feel low again. Got a lot going on but trying not to panic. Do other members find they have peaks and troughs in their depression? My GP mentioned bipolar but I am in my fifties so I feel i would have already had a diagnosis of this, although it is in my family. Taking 40mg of fluoxetine and really dont want any more. Ant advice or support would be great.
